WINDOW v VENTILATOR.

Application fil'edqanuary 19 24. SerialNo; 686,321.;

To all whom it may sconce m: Be it known that I, JOHN New York'city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and-useful Improvements in Window Ventilators,

' abledirectidrafts of cold air when the lower sash is raised.

Among-the objects of the invention is to providea' ventilator that is adjustable both as tolength for fitting any reasonable vari- 'ation in width of the windowand also as to inclination toward or from the plane of the window sash to vary the degree of opening and also the direction of i the current of fresh {air admitted thereover.

Withthe foregoing-and other objects in view the invention consists in the arrangement a'nd combination ofparts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, fstill for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is an outside elevation showing my improvement applied adjacent to the bottom of an open window. 1 Fig. 2 is a fragmentary enlarged view in perspective of the upper part of the ventilator andin'dicating' especially the longitudinal adjustment of the canopy.

Fig. 3 is a view of the left end of the ventilator as seen from the inside and with parts in section on the line 3-3 of Fig, 1. Fig. is an inside perspective of the central part of the device, viewed from the same general direction as Fig. 3, and with parts in section on the line 4.-4L of Fig. 1.

Referring now more specifically to the drawings, it will be understood that the adjustable ventilator is designed tofbe sup- 7 BELLOOGHIO, a citizen of the United States, residing at ported uponthe window sill S beneath just within the window of which theilower sash is indicated at in raised position.

The improvement comprises a substantially rectangular open frame-having upper and'lower channel bars 10* and 11 respectively, the channelsbe'ing directed toward each other, and these parts are connected or held in fixedspacedparallel relation by a plurality ofstays 12, at eachend of the frame, and. 13 between the ends. These parts may be made of sheet metal or any other suitable material and are sufficiently.

strong and rigid for their purpose without being bulky or expensive, and they maybe attached to one another by riveting, brazing, or otherwise, making a permanent structure. The frame so made s adapted'to be held in substantially erect position upon the sill S but at any desired inclination 'in-.

ward from the plane of the windowsash.

To this end I-show for each 1 stay 12a foot 14 of channel construction made preferably similar to the stay 12 of channel construc tion. A. brace or link 15 is pivoted permanently at 16 between the ends of the stay and is connected adjustably to theifoot 14 as by means of a pivot pin 17 insert-able through any selected pair of holes 18 formed through the foot parallel to the window. lower end as by a pivot pin 20 through the end pair of holes in the foot, and at its upper end the brace carries a cross pin'21 engageable selectively in any pair of: notches 22 formed in the upper portion of. the stay 12. By this construction it is apparent that the frame may be tilted toward or from the plane of the window and held inrigid vAbrace 1,9 isconnected at its position by a variation in the contact or connection points of the parts just dev scribed. 7 p

The brace for the central stay 13 is preferably made of two longitudinally adjustable upperand lower parts 23 and 24:, the

one connected pivotally at 25'to a lug 26 extending laterally from the upper end of the stay and having a loop or keeper 27: at

its lower end'slidably embracing the brace part 24. The variation in length ofpthis brace is effected by means of'registering holes 28 through the overlapping parts and through any selected pair of which a pin 29 co-operates. A foot 30 is pivotally connected to the lower end of the brace and has bearing upon the window sill. These several feet 14 and 30 are preferably faced with rubber, felt, or the like at 31 to prevent the marring of the woodwork.

The main portion of the draft guard or means for directing the current of fresh air through the open window comprises two longitudinally adjustable panels 32 made preferably of transparent material such as celluloid, glass, or the like.v Each of these panels 32 is connected to upper and lower "guide-strips 33 and 34 respectively arranged preferably flush with the outer end of the panel asshown in Fig. 3. These guide strips are connected to the panelas by rivets 35 through one flange thereof while another flange portion beyond the panel is mounted movably or slidably inthe channel of the adjacent frame rail 10 or 11.

At the outer end of each panel there is fixed thereto an end piece 36 the main portionwofwhich lies in a verticalplane and is in the form of a sector of a circle having an arc sh aped upper end, and is provided on the inner edge with an angularly formed flange 37 for attachment to the end of the panel embraced thereby. This flange 37 constitutes means for attachment of the end piece to the rails 33 and 34 also.

Adjacent to the outer side of the top of each panel is a canopy 38 made preferably of sheet metaland having a transverse curvature'corresponding to the top end of the end pieces 36. Each canopy part is provided with anupstandingflange 39 at the rail 33 and secured thereto. Toward the inner end,

however, of each canopy or along the middle portion of the entire device each canopy is cutaway as at 40, and the adjacent ends of these canopies overlap each other slidably along thecut away portion as also do the panels 32. While the panels and attached end pieces and canopies are held in the channels of the rails '10 and 11 in relatively fixed position as to their relation to the window it is plain that they are adjustable endwise relatively to the frame and to each other so as'to approximately fill the window space laterally or as much thereof as desired and also to adapt the ventilator to various widths of. windows. The main purpose of the canopies 38 isto prevent rain and snow from dashing or blowing inward over the panels 32 as would be likely to'take place if the canopies were not present. The device, however, will be adjusted so as to afford any desired amount of space between the outer edge of the canopies and the bottom of the window sash. Any blast of wind or wet weather, however, will be deflected downward and outward again by striking along the under surfaces of the canopies. Ears or projections 36 are formed on and extend laterally from the end pieces 36 for direct engagement with the window frame, the ears projecting into the channels along which the lower sash slides. By this means the ventilator is prevented from being blown by storm or otherwise from its intended position. These .parts are made to cooperate with the window frame by means of the longitudinal adjustment of one or the other of the slidable parts.

I claim:

1. In a window ventilator, the combination of a frame comprising upper and lower channel rails, means including upright stays attached to the rails and serving to hold them in fixed spaced parallel relation to each other, brace means for the frame, and wind shield means carried by the rails, said brace means including adjustable members pivotally connected to the stays.

In a window ventilator, the combination of a frame comprising upper and lower channel rails, means including upright stays attached to the rails and serving to hold them in fixed spaced parallel relation to each other, brace means for theframe, and

windshield means carried by and adjustable lengthwise along the rails, said brace means for the frame including adjustable members pivotally connected to the stays and including pivotally connected feet at their lower ends for engagement with the wi-ndowsill.

3. In a window ventilator, the combination of a frame. comprising upper and lower channel rails, means including upright stays attached to the rails and serving to hold them in fixed spaced parallel relationto each other, brace means for the frame, and windshield means carried by and adjustable lengthwise along the rails, said windshield construction including a pair of transparent panels, guide means attached to the-upper and lower edges of each panel and having slidable engagement with the frame rails, and each panel having a triangular shaped end piecelying mainly in a plane at right angles to the panel and adapted to fit against the side of the window frame.

4. A window ventilator comprising a pair of rectangular panelsoverlapp'ing each other at their inner ends, a frame, a pair of guide members fixed to the upper and lower edges of the panels and slidable along the frame, a canopy for each panel of arc shape in cross section and including an upwardly extending flange along its inner edge fastened to the'guide member at the upper edge of the panel, and an end piece for each panel of tapered form and having a rounded upper end conforming to the canopy adjacent thereto, substantially as set forth.

5. A window ventilator comprising a pair of panels adapted to overlap each other at their inner ends, a frame, a pair of guide members fixed to the upper and loweredges of the panels and slidable along the frame, and a canopy for each panel fastened to the guide member at the upper edge of the panel, portions of said canopies adjacent to each other being cutaway along the line of atends of the ca nopies being adapted to overlap along the cut away portions.
